摘要： In order to reduce waveform distortion caused by higher harmonic components of rectangular waveforms reduced as compared with fundamental frequency component when a wireless digital signal is directly and wirelessly transmitted and received by baseband transmission, an antenna apparatus includes a dielectric substrate including a ground conductor formed on a back surface thereof, and a radiation conductor formed on a front surface of the dielectric substrate. Upon directly transmitting and receiving a wireless digital signal via a feed point of the radiation conductor, formation of notched portions at sides of the radiation conductor, which intersect an electric field plane defined by an electric field when the antenna apparatus is excited, leads to reduction in the waveform distortion of waveform of the transmitted wireless digital signal.

摘要： The present invention provides an antenna in which, on a dielectric substrate 1 having a back face on which a grounding conductor plate 14 is disposed, a plurality of conductor elements 12 are arranged in a matrix of rows and columns. Each of the dielectric elements 12 has a size which cannot function as an antenna. Above the conductor elements 12, a connecting element 13 overlapping two adjacent conductor elements 12 is disposed. Among the connecting elements 13, some cause the conductor elements 12 on both sides to be in a conductive condition, and others cause the conductor elements 12 on both sides to be in a non-conductive condition. The switching between the conductive and non-conductive conditions between the conductor elements 12 can be dynamically performed by a switching element.
